PROCESS OPTIMIZATION

Inferentials are real-time signals typically implemented in the process control network (PCN) and used to monitor, control and optimize product qualities for multi-draw fractionators and two-product towers in refineries and petrochemical plants.

Generalized Cutpoint Control (GCC)

GCC is a compact, integrated package of constraints, dynamics, manipulated variables, and inferential models. To increase its speed and simplicity, GCC takes into account a finite set of instrument measurements with no redundancy.

Generalized Distillation Short-Cut (GDS)

GDS is an inference model for predicting distillation top and bottom product purities. It has been implemented on a wide variety of distillation equipment, from simple light-ends columns to superfractionators.
